Test of Canon 100mm EF Macro lens
Decided to snap some pictures today to test out my 100mm Macro lens. Set ISO to 100, Apeture priority starting at F/2.8
So, as can be seen here, increasing the F number (decreasing the apeture) decreases sharpness, but increases the depth of field. The first picture was taken at F/2.8, the second at F/32. What you cant tell, since I had the exposure set for apeture priority is the amount of time increased dramatically between these two extremes; from 1/80th of a second to 1.3 seconds. So, increasing F#=decreasing apeture size=decreasing light = increasing DOF.
Here is a pic, same settings as the first above, only the ISO is set to 1600
Now, the real problem here with these pictures is the yellow-orangish hue of the light. I realized later I had the white balance set for sunny day. Setting the WB to AWB and removing the UV filter gives me this result:
